Title: HF lead through capacitor - has flanges removed after construction to leave centre spindle in outer can type separated by dielectric
Inventor: BUEPPELMANN HANS-GEORG ING GRA
IPC: H01G4/35
Filed: 1978-12-21
Abstract: The h.f. lead through capacitor is a central metal spindle inserted into an outer conductor can and with pressure injected resin in the cavity between to form the dielectric. The object is constructional simplicity. The central conductor is a metal spindle (1) with a bulbous section (3) with removable flanges (2) which extend a little (A) beyond the edge of the bulbous part, and act as spacing formers. The central unit is inserted into the can outer capacitor plate (4) and a moulding resin (8) is pressed into the space (A) between inner and outer. When the resin has set the flanges (2) are removed and the ends 'finished off' so that in the final capacitor the resin dielectric extends just over the shoulder of the bulbous part of the central spindle plate. The central spindle is hollow so that a transistor or diode may be internally mounted.

Title: Rotary ring hearth furnace - where loading and unloading tongs are each mounted on trolleys driven through an arc so billets can be located obliquely on hearth
Inventor: SCHEURER WERNER DR ING
IPC: F27B9/16
Filed: 1979-01-05
Abstract: Workpieces, e.g. billets, are fed by tongs through a charging door onto the hearth, which carries the billets through almost a complete circle to a discharge door fitted with a second pair of tongs employed for removing the heated billets. Both pairs of tongs or their guides can be swivelled through a horizontal arc, so the billets can be located obliquely w.r.t. radial lines across the hearth. The pref. furnace is fitted with two pairs of curved rails, each carrying a trolley fitted with a pair of tongs. Trolleys are driven along their rails to alter the angle of the tongs w.r.t. radial lines through the charging and discharging doors. Billets which are longer than the radial width of the hearth can be heated; and max. utilisation of the hearth can be achieved with billets of different length; e.g. a billet 3.5 metres long can be heated on a hearth with radial width 2.3 metres.

Title: Prevention of temperature effects on fibre optic polarisation - has detector sensing changes in light polarisation caused by variation in tensional stress due to temperature
Inventor: BARGMANN WOLF-DIETER
IPC: G01R15/24
Filed: 1979-06-20
Abstract: The detector senses changes in the linear polarisation of light in a helically wound optical fibre due to temperature variation. The wound fibre (8) is typically used in cement level measurement in high voltage lines (9). Changes in polarisation due to the effect of temperature on the tensional stress in the film are detected by transmitting light from a photo-emitting or lasing diode (1) through a polarising filter (3) and optical system (4) into the grounded end of the fibre (6). An optical divider at the fibre input passes part of the transmitted light and reflected light from the metalised free end (12). of the film through a second filter (13) to a detector (14). The metalising may be replaced by an optical system and a mirror.

Title: Motor vehicle seat belt fastening lock - has two angled slopes on bolt engaging tongue, linked by vertical plane
Inventor: MUSKAT KURT
IPC: A44B11/25
Filed: 1979-06-23
Abstract: A spring-stressed closing bolt is brought into engagement with a hole in a lock tongue, which has an ejection spring, and a release device slides perpendicular to the tongue, which has a slope to activate the bolt, in a securing lock, esp. on safety belts in motor vehicles. The bolt (3) is turned by the release device (9,6). On the side facing the tongue (14) it has a second inclined plane' turned between pref. 45 deg. and 135 deg., close to the tongue slope.

Title: Monitoring open circuits in parallel loads in vehicles - using analyser-indicator connected to generator and measurement transformers
Inventor: STEINKE LEO
IPC: G01R31/02
Filed: 1979-08-23
Abstract: An open circuit monitor for two or more electrical loads connected in parallel in a vehicle dispenses with the need for a reading wire necessary in conventional arrangements with electromagnetic signal transfer for conducting the monitoring signal to the evaluation circuit. This results in economy. In particular, when only two parallel loads are being monitored, only one transfer device is required instead of two. The evaluation circuit (22) and indicator (25')are connected to the alternating current generator. When only two loads are monitored a single transformer (16) is required. Its primary coil (18) is connected to the generator (19) whilst its secondary winding consists of the wires connected to the two loads. Each transformer has a closed core and the generator is medium frequency type.

Title: Welded lattice girder struts nodal joint - has one strut end bent along chord gravity line while other runs straight
Inventor: MITTELSTAEDT KLAUS
IPC: E04C3/04
Filed: 1979-11-27
Abstract: Ends of two individual struts are directly joined to chords, on lattice girders with zigzag or saw-tooth strutting. The end (49) of one of the two struts (41,42) is bent back (48) with the chord's (40) gravity line (46) at the intersection (43) of its own gravity line (44), and continues straight along it. The end of the other, running straight, meets these two gravity lines. The meeting place (47) of the two struts, and the end of the continued first strut, are welded to each other and to the chord structure. The ends may also be welded to the chord structure in their neck area. This permits construction of nodal connections regardless of chord profile height, with adequate weld seam length.

Title: Environmentally harmless road salting system - uses mats or sheets laid out on ground and including depressions holding salt
Inventor: REPPERT RUEDIGER LOTHAR VON
IPC: E01H10/00
Filed: 1980-01-18
Abstract: The system ensures that no environmental hazards are associated with salt which is distributed, with long-term effectiveness, for keeping surfaces free from ice and snow. Weatherproof mats, foil sheets or panels made of plastics, metal, concrete or other materials, are spread out on paths, steps, roads or squares. These contain hemispherical, oval or polygonal depressions, close together and impermeable to water. Salt, spread for thawing, falls into these and remains there.

Title: Rolled strip pickling plant - with floating box shaped fitments to reduce evaporating surface area
Inventor: MINDT WALTER
IPC: C23G3/02
Filed: 1980-03-01
Abstract: The Parent Patent described a plant for the chemical or electrochemical surface treatment of rolled stock by acid, alkaline or other liquids at temperatures above room temperatures, specially in strip pickling plant, where the evaporating surface of the treatment liquid is kept to a minimum by built-up fitments. In this addn. these fitments are designed as displacement elements which dip to a greater or lesser degree into the liquid. They have preferably a box shape and take up as much as possible of the horizontal cross-section of every tank. These built-up fitments have a great effect on the heat loss due to evaporation and reduce the energy and material consumption.
